Description

Technical Field

[0001] This invention relates to the field of material mixing technology, and in particular to a variable frequency mixer with shock absorption and buffer on the barrel wall. Background Technology

[0002] The square cone mixer is a novel material mixer commonly used in industries such as pharmaceuticals, chemicals, metallurgy, food, light industry, and feed. As a cone-shaped mixer, it can mix powders or granules very evenly, enhance the dispersibility of materials, shorten mixing time, and has the advantages of low energy consumption. It achieves satisfactory mixing results. The working principle is that the materials are loaded into a square cone-shaped sealed mixing drum. The symmetrical axis of the hopper forms an angle with the axis of rotation. Different components of the materials move in three-dimensional space within the sealed material gate, producing a strong tumbling and diffusion effect, achieving the best mixing effect.

[0003] However, existing cone mixers sometimes experience the problem of materials separating again after they have already been mixed, resulting in poor mixing performance. Summary of the Invention

[0042] (III) Beneficial Effects

[0043] The above-described technical solution of the present invention has the following beneficial technical effects:

[0044] The inventors of this invention discovered through analysis that when using a cone mixer, as the cone mixing drum continuously rotates, the inner wall of the cone mixing drum resonates due to the impact of the internal materials. Furthermore, as the mixing time increases, during each impact of the materials on the cone mixing drum, not only do the cone mixing drum and the materials resonate, but the cone mixing drum also resonates with the entire mixing equipment. This resonance of the entire equipment severely exacerbates the reseparation of the mixed materials. As the rate of material separation gradually exceeds the mixing rate of the cone mixing drum, significant material separation occurs, resulting in poor mixing performance of the cone mixer.

[0045] To address this issue, the present invention provides multiple baffles within a cone-shaped mixing drum, each baffle spaced apart from all the inner walls of the drum. These baffles are then joined together at the material cylinder wall within the drum, forming an inner lining. This spacing between each baffle and the inner walls absorbs the impact of materials on the drum's inner walls during tumbling, providing vibration damping. Furthermore, the elastic deformation of the baffles upon impact with the mixed materials effectively absorbs the vibrations, altering the vibration frequency and preventing resonance within the drum and the entire equipment. This eliminates the reseparation of the mixed materials caused by resonance, resulting in a better mixing effect and resolving the technical problem of existing cone mixers where mixed materials separate again during mixing.

[0073] The invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0074] For existing components that do not involve the improvements of this invention, they will be briefly described or not described at all, while the focus will be on describing the components that have been improved relative to the prior art.

[0075] See Figures 1 to 11 This invention provides a variable frequency mixer with shock absorption and buffer on the barrel wall, comprising:

[0076] 100 racks;

[0077] A cone-shaped mixing tank 300 is installed in the frame 100, and the cone-shaped mixing tank 300 is used to load the mixed materials; and

[0078] Multiple partitions are spliced ​​together and arranged on the wall of the material cylinder inside the square cone mixing barrel 300, and the multiple partitions are spaced apart from all the inner walls of the square cone mixing barrel 300;

[0079] During the tumbling process of the square cone mixing barrel 300, the partition is used to undergo elastic deformation when impacted by the mixture.

[0080] The inventors of this invention discovered through analysis that when using a cone mixer, as the cone mixing drum 300 continuously rotates, the inner wall of the cone mixing drum 300 resonates due to the impact of the internal materials. Furthermore, as the mixing time increases, during each impact of the materials on the cone mixing drum 300, not only do the cone mixing drum 300 and the materials resonate, but the cone mixing drum 300 also resonates with the entire mixing equipment. The resonance of the entire equipment severely exacerbates the reseparation of the mixed materials. As the separation speed of the materials gradually exceeds the mixing speed of the cone mixing drum 300, significant material separation occurs, resulting in poor mixing effect of the cone mixer.

[0081] To address this, the present invention provides multiple baffles within a conical mixing drum 300, each baffle spaced apart from all inner walls of the drum. These baffles are then joined together at the material cylinder wall within the drum, forming an inner lining. This spacing between each baffle and the inner walls of the drum absorbs the impact of materials on its inner walls during tumbling, providing a vibration damping effect. This is particularly effective when the baffles are impacted by the mixture. The elastic deformation fully absorbs the impact vibration of the material on the inner wall of the cone mixing drum 300 during the tumbling process, changes the vibration frequency of the cone mixing drum 300, and thus avoids resonance after the cone mixing drum 300 is impacted by the material, and also avoids resonance between the cone mixing drum 300 and the entire equipment. This eliminates the reseparation of the mixed materials caused by resonance, enabling the cone mixer to achieve a good mixing effect on the material, thereby solving the technical problem of existing cone mixers where the mixed materials separate again during material mixing.

[0082] (Not shown in the attached diagram) Furthermore, the partition is made of a material suitable for manufacturing medical devices. Utilizing the properties of this material, the elastic deformation capacity of all partitions is improved, thereby enhancing the absorption of material impacts on the inner wall of the cone mixing tank 300 during tumbling. This significantly reduces resonance between the cone mixing tank 300 and the material, as well as resonance between the cone mixing tank 300 and the entire mixing equipment.

[0083] See Figures 1 to 11 Furthermore, the partition includes a top partition 600, multiple side partitions 400, and multiple bottom partitions 500, which are assembled to form the material cylinder.

[0084] The top partition 600 is disposed inside the large end of the square cone mixing barrel 300, and the large end of the square cone mixing barrel 300 and the top partition 600 are spaced apart to form a closed top cavity 610.

[0085] Multiple side partitions 400 are disposed within the square body 310 of the pyramidal mixing tank 300 below the top partition 600. The multiple side partitions 400 and the top partition 600 are joined together to form a cubic structure with an open bottom. The multiple side partitions 400 and the inner wall of the square body 310 of the pyramidal mixing tank 300 are spaced apart and form a sealed side cavity 410.

[0086] Multiple bottom partitions 500 are disposed at the open ends of the cube structure. The multiple bottom partitions 500 are spliced ​​together to form the small end of a square pyramid. The multiple bottom partitions 500 are spaced apart from the inner wall of the cone end of the square pyramid mixing tank 300 and form a sealed bottom cavity 510.

[0087] The top cavity 610, the side cavity 410, and the bottom cavity 510 are interconnected only through multiple connecting structures.

[0088] The cone mixer with vibration damping and buffering function on the barrel wall also includes an adjustment mechanism 700, which cooperates with multiple connected structures to adjust the connecting area of ​​the multiple connected structures.

[0089] The side cavity 410 and the bottom cavity 510 have square cross-sections, and the cross-sections are planes perpendicular to the axial direction of the square cone mixing barrel 300.

[0090] During the process of material impacting the baffle, the baffle's buffering and vibration reduction effect relies on the baffle's own elastic deformation capacity. On the other hand, during the process of the baffle being impacted by the material and undergoing elastic deformation, the air pressure in the top cavity 610, the side cavity 410, and the bottom cavity 510 also provides support and buffering for the baffle. The adjustability of the air pressure in the top cavity 610, the side cavity 410, and the bottom cavity 510 is stronger than the adjustability of the baffle's own elastic deformation. Therefore, for different types of materials being mixed, the buffering performance of the conical mixing tank 300 can be adjusted by regulating the air pressure in the top cavity 610, the side cavity 410, and the bottom cavity 510.

[0091] Therefore, the adjustment mechanism 700 is used in conjunction with multiple connecting structures to adjust the connecting area of ​​the multiple connecting structures. The top cavity 610, the side cavity 410, and the bottom cavity 510 are only interconnected through multiple connecting structures. Therefore, by adjusting the connecting area of ​​the multiple connecting structures, the internal air pressure of the top cavity 610, the side cavity 410, and the bottom cavity 510 during the impact of materials can be changed, thereby making appropriate adjustments based on the structural characteristics of the cone mixing tank 300 during the impact. For example, for the large end of the cone mixing tank 300, since the contact area with the material is the largest during the impact, the impact force is also the greatest. Therefore, the connecting area between the top cavity 610 and other cavities can be reduced by the adjustment mechanism 700, so that when the top partition 600 is impacted, the gas inside the top cavity 610 is not easy to flow, thus having relatively sufficient gas to cope with the frontal impact of the material, thereby improving the vibration damping and buffering capacity of the large end of the cone mixing tank 300.

[0092] See Figures 1 to 11 Furthermore, a column structure 312 is provided inside the side cavity 410. The column structure 312 is a hollow column and is located at the corner of the side cavity 410. The top of the column structure 312 extends into the top cavity 610, and the bottom of the column structure 312 extends into the bottom cavity 510.

[0093] The plurality of the connected structures include:

[0094] A top opening 314 is provided on the top side wall of the column structure 312, and the top opening 314 is used to communicate the top cavity 610 with the inside of the column structure 312.

[0095] A side opening 313 is provided on the side surface of the column structure 312, and the side opening 313 is used to communicate the side cavity 410 with the inside of the column structure 312.

[0096] A bottom opening 315 is provided at the bottom end of the column mechanism, and the bottom opening 315 is used to communicate the bottom cavity 510 with the column structure 312.

[0097] The adjustment mechanism 700 is a hollow column. The adjustment mechanism 700 passes through the top of the column structure 312 from the outside of the large end of the square cone mixing barrel 300 and is inserted into the column structure 312. The adjustment mechanism 700 is used to rotate relative to the column structure 312.

[0098] The top sidewall of the adjustment mechanism 700 is provided with a top through hole 720, which is used to align and communicate with the top opening 314;

[0099] The adjustment mechanism 700 has a side through hole 710 on its side wall, which is used to communicate with the side opening 313;

[0100] The adjustment mechanism 700 has a bottom through hole 730 at its bottom end, which is used to communicate with the bottom opening 315.

[0101] Taking advantage of the fact that the adjusting mechanism 700 is fitted inside the column structure 312, by rotating the adjusting mechanism 700, the top through hole 720 on the surface of the adjusting mechanism 700 is aligned and connected with the top opening 314 of the column structure 312. At the same time, the side opening 313 of the column structure 312 is aligned and connected with the side through hole 710 of the adjusting mechanism 700, and the bottom opening 315 of the column structure 312 is aligned and connected with the bottom through hole 730 of the adjusting mechanism 700. Since both the adjusting mechanism 700 and the column structure are hollow columns, the top cavity 610, the side cavity and the bottom cavity are connected to each other by the column structure 312 and the adjusting mechanism 700. When it is necessary to adjust the interconnection area of ​​the top cavity 610, the side cavity 410 and the bottom cavity 510, the adjustment mechanism 700 is rotated relative to the column structure 312, thereby changing the interconnection area between the top through hole 720 and the top opening 314, the interconnection area between the side opening 313 and the side through hole 710, and the interconnection area between the bottom opening 315 and the bottom through hole 730, so that these interconnection areas become larger or smaller, thereby adjusting the air pressure in the top cavity 610, the side cavity and the bottom cavity when the material impacts each partition.

[0102] See Figures 1 to 11 Furthermore, there are two column structures 312, which are respectively located at opposite corners of the cube structure. There are two adjustment mechanisms 700, which are respectively inserted into the corresponding column structure 312 through the top of the column structure 312 from the outside of the large end of the square cone mixing barrel 300.

[0103] There are two side partitions 400. Each side partition 400 is a rectangular plate with its long side bent into an L-shape. The wide side and the bending line of the side partition 400 are vertically arranged. The two side partitions 400 are symmetrically arranged about the diagonal of the cube structure. The two column structures 312 are sandwiched between the two side partitions 400.

[0104] There are two side openings 313, which are located on both sides of the column structure 312 respectively. Each side opening 313 is arranged facing a different side of the square body 310 of the square cone mixing barrel 300. There are two side through holes 710, which are respectively opened on different sides of the adjustment mechanism 700.

[0105] Preferably, the side opening 313 is a vertically arranged elongated through hole, and the side through hole 710 is also two vertically arranged elongated through holes.

[0106] In this invention, only two column structures 312 are provided, respectively located at opposite corners of the cube structure, and the long side of the side partition 400, which is a rectangular plate, is bent into an L-shape. This simplifies the number of side partitions 400 and column structures 312, facilitating installation. Furthermore, it divides the entire side cavity 410, which has a rectangular cross-section, into two L-shaped cross-sections. The two column structures 312 and corresponding adjustment mechanisms 700 regulate the internal air pressure of the two divided side cavities 410 when impacted, thus refining the air pressure regulation method within the entire side cavity 410 to meet the needs of mixing different materials.

[0107] See Figures 1 to 11 Furthermore, there are two bottom partitions 500, each of which is a quadrilateral plate bent along its diagonal. The two bottom partitions 500 are joined together along the two diagonal edges of the square pyramid.

[0108] The inner wall of the cone end of the square cone mixing tank 300 is provided with two support rods 322. The two support rods 322 extend along the two diagonal edges of the square cone, and the bend of each bottom partition 500 is located on the long side of the corresponding support rod 322.

[0109] By using two bottom partitions 500, each of which is a quadrilateral plate bent along its diagonal, the assembly method of the bottom partitions 500 is simplified, and the installation difficulty and assembly error are reduced.

[0110] In addition, considering that the bottom partition 500 is spliced ​​into the pointed end of a square pyramid, multiple inclined surfaces are simultaneously impacted by the material during the material flipping process, so the vibration is small and the required buffering force is small. Therefore, a support rod 322 can be set in the bottom cavity 510 to ensure effective support for the bottom partition 500 at the bottom cavity 510 while ensuring a good buffering effect.

[0111] Meanwhile, by utilizing the feature that the two bottom partitions 500 are spliced ​​together along the two diagonal edges of the square cone, the bending of each bottom partition 500 is located on the long side of a corresponding support rod 322, thereby effectively reducing the number of corresponding support rods 322 and the splicing weight of the bottom partitions 500, thus reducing the weight of the square cone mixing tank 300 and reducing the power consumption of the entire device to drive the square cone mixing tank 300 to flip.

[0112] See Figures 1 to 11Furthermore, the square body 310 of the cone-shaped mixing tank 300 has a shell structure. The top and bottom of the square body 310 are respectively provided with transverse protrusions 360, which protrude into the square body 310 and extend along the length of the square body 310. The upper and lower sides of the side partition 400 are respectively connected to the corresponding transverse protrusions 360. The side partition 400, the square body 310 of the cone-shaped mixing tank 300, and the two transverse protrusions 360 form a sealed side cavity 410.

[0113] The cone-shaped mixing tank 300 has a discharge port structure 321 inside its cone end. The discharge port structure 321 is a sleeve that extends into the cone end of the cone-shaped mixing tank 300. The top end of the bottom partition plate 500 is connected to the transverse convex rib 360 on the bottom side of the square body 310 of the cone-shaped mixing tank 300. The bottom end of the bottom partition plate 500 is connected to the top end of the discharge port structure 321. The bottom partition plate 500, the discharge port structure 321, and the transverse convex rib 360 on the bottom side of the square body 310 of the cone-shaped mixing tank 300 form a closed bottom cavity 510.

[0114] The transverse convex rib 360 facilitates the assembly and positioning of the side partition 400 and the bottom partition 500, and ensures the effective sealing of the bottom cavity 510 and the side cavity 410.

[0115] See Figures 1 to 11 Furthermore, the large end of the square cone mixing tank 300 is provided with a cover plate 330. The bottom surface of the cover plate 330 is recessed upward to form a cavity. A limiting protrusion 332 is connected to the bottom edge of the cavity. The limiting protrusion 332 extends along the bottom edge of the cavity. The top partition plate 600 is placed inside the cavity and above the limiting protrusion 332. The limiting protrusion 332 is used to restrict the top partition plate 600 to move only up and down. The top partition plate 600, the cover plate 330, and the limiting protrusion 332 form a sealed top cavity 610.

[0116] The top surface of the cover plate 330 is provided with a top exhaust control head mechanism 341, which is connected to the top cavity 610.

[0117] On the one hand, considering the large vibration of the top partition 600 when it is subjected to frontal impact from materials, the top partition 600 is completely confined within the concave cavity and can move up and down relative to the concave cavity. This allows the top partition 600 to move within the concave cavity when impacted by materials, thereby fully absorbing the impact force of the materials. Furthermore, the limiting protrusion 332 prevents the top partition 600 from detaching from the cover plate 330.

[0118] On the other hand, the exhaust speed of the gas in the top cavity 610 is controlled by the top exhaust control head mechanism 341, thereby controlling the gas exhaust speed in the top cavity 610 according to the characteristics of different materials impacting the top baffle 600, thereby controlling the buffering force of the top baffle 600.

[0119] See Figures 1 to 11 Furthermore, a low-pressure head mechanism 350 is provided on the outer surface of the cone end of the square cone mixing barrel 300 or on the outer surface of the square body 310 of the square cone mixing barrel 300.

[0120] The outer surface of the cone end of the square cone mixing barrel 300 or the outer surface of the square body 310 of the square cone mixing barrel 300 is connected to the housing of the low-pressure head mechanism 350. The open end of the housing of the low-pressure head mechanism 350 is connected to the bottom cavity 510 or the side cavity 410. The push rod of the low-pressure head mechanism 350 is placed in the low-pressure head housing, and one end of it is in contact with the corresponding bottom partition 500 or the side partition 400. The low-pressure head mechanism 350 is an airbag type, a cylinder type or an electromagnetic type. The low-pressure head mechanism 350 is used to push the bottom partition 500 or the side partition 400.

[0121] When the bottom partition 500 or the side partition 400 is impacted by material, the push rod of the low-pressure head mechanism 350 will also be compressed into the housing of the low-pressure head mechanism 350.

[0122] The low-pressure head mechanism 350 here has a buffer cavity inside its housing. The opposite end of the push rod of the low-pressure head mechanism 350 is connected to a piston and placed in the buffer cavity. So when the push rod is squeezed by the corresponding partition, the push rod pushes the piston to squeeze into the buffer cavity, thereby using the air pressure in the piston and the buffer cavity to form a buffering effect.

[0123] The low-pressure head mechanism 350 pushes against the bottom partition 500 or the side partition 400, thereby adjusting the shape of the bottom partition 500 or the side partition 400 before material impact. This allows for targeted adjustment of the partition shape before impact for different materials, effectively handling material impact. After impact, the low-pressure head mechanism 350 pushes against the bottom partition 500 or the side partition 400, causing them to quickly return to their original position.

[0124] See Figures 1 to 11 Furthermore, a lateral exhaust control head mechanism 342 or a bottom exhaust control head mechanism 343 is provided on the outer surface of the cone end of the square cone mixing barrel 300 or on the outer surface of the square body 310 of the square cone mixing barrel 300.

[0125] The bottom cavity 510 or the side cavity 410 is connected to the side exhaust control head mechanism 342 or the bottom exhaust control head mechanism 343.

[0126] The gas discharge speed of the side cavity 410 or bottom cavity 510 is controlled by the side exhaust control head mechanism 342 or the bottom exhaust control head mechanism 343, thereby controlling the gas discharge speed in the side cavity 410 and bottom cavity 510 according to the characteristics of different materials impacting the corresponding baffles, and thus controlling the buffering force of the corresponding baffles.

[0127] See Figures 1 to 11 Furthermore, the aforementioned variable frequency mixer with shock absorption and buffer on the barrel wall also includes a fixing frame 200. The fixing frame 200 has a square frame structure and is provided with a slot 210. The outer wall of the square cone mixing barrel 300 is provided with a retaining ring 311. The retaining ring 311 has a convex ridge structure and extends along the long side of the square cone mixing barrel 300. By placing the retaining ring 311 in the slot 210, the square cone mixing barrel 300 is prevented from detaching from the fixing frame 200.

[0128] The fixing frame 200 is provided with a hydraulic clamp 211, which is placed in the clamping groove 210. The clamping ring 311 has a positioning hole, and the hydraulic clamp 211 is used to extend into the positioning hole or retract into the clamping groove 210.

[0129] The fixing frame 200 is connected to the frame 100, and the fixing frame 200 is used to drive the square cone mixing barrel 300 to rotate relative to the frame 100.

[0130] Specifically, the mounting bracket 200 is connected to the frame 100 via a rotating shaft 220.

[0131] The retaining ring 311 is placed in the slot 210 to prevent the square cone mixing barrel 300 from detaching from the fixing frame 200. The hydraulic clamp 211 is used to extend into the positioning hole to prevent the retaining ring 311 from moving relative to the slot 210, thereby improving the fixing effect of the fixing frame 200 on the square cone mixing barrel 300.
